Wilsons Disease

Wilson's disease is a genetic disorder marked by the excessive accumulation of copper in the body, causing harm to the liver and nervous system. Symptoms may include Kayser-Fleischer rings around the eye, confusion, behavior changes, speech difficulties, hand tremors, weakness, and jaundice. Treatment typically involves chelation therapy to bind copper to medication, facilitating its removal from the body. The primary drug class used for treatment is metal chelators, which specifically aid in this copper elimination process.

Causes

Wilson's disease is caused by a genetic mutation in the ATP7B gene, which regulates copper levels in the body. It is hereditary and passed down in an autosomal recessive pattern. Key points regarding the causes include:

• Genetic Defect: A defect in the ATP7B gene prevents proper copper removal from the body.

• Inheritance: The disease is autosomally recessive, requiring mutated copies from both parents to manifest.

• Disruption of Copper Elimination: Normally, the ATP7B gene assists in transporting copper from the liver into bile for elimination.

• Copper Accumulation: Impaired elimination leads to copper buildup, primarily in the liver, and eventually in other body parts like the brain and eyes.

• Toxicity and Symptoms: The copper buildup is toxic, leading to the symptoms and complications in affected individuals.

Symptoms

Wilson's disease leads to excessive copper buildup, mainly impacting the liver, brain, and eyes. Although symptoms can appear between ages 5 and 35, they vary, including:

• Liver-related symptoms: Fatigue, jaundice (yellowing of skin and eyes), and fluid accumulation in the abdomen or legs.

• Neurological symptoms: Speech difficulties, coordination issues, muscle stiffness, tremors, and potential mental health challenges like depression or psychosis.

• Ocular symptoms: Notable are Kayser-Fleischer rings, golden-brown rings around the iris of the eye.

Consult a healthcare professional immediately if these symptoms occur, especially if there's a family history of Wilson's disease.

Diagnosis

Diagnosing Wilson's disease requires a thorough approach since its symptoms often resemble other liver conditions. Physicians typically conduct blood and urine tests to assess liver function and measure copper and ceruloplasmin levels—a copper-transporting protein. Eye exams may detect Kayser-Fleischer rings. In certain cases, a liver biopsy may be conducted to confirm excessive copper in liver tissue. Genetic testing might be utilized to identify the mutations responsible for Wilson's disease and is particularly beneficial for family screening. Early diagnosis is crucial to prevent significant organ damage.

Treatments

Managing Wilson's disease involves ongoing treatment to control excess copper in the body. This primarily involves copper chelating agents, which aid in copper excretion through urine. Common agents include Penicillamine and Trientine, with trientine generally preferred due to fewer side effects. Important to note is that penicillamine might initially worsen neurological symptoms, necessitating close monitoring. Zinc acetate is also employed to prevent copper from being absorbed from dietary sources, typically after initial copper reduction. Lifelong treatment is necessary to maintain safe copper levels, and in severe cases with significant liver damage, a liver transplant may be necessary. Patients are advised to avoid copper-rich foods like shellfish and liver and to regularly test tap water for copper content. Continuous medical oversight is vital to managing this genetic disorder and preventing complications.

Medications

Treatment of Wilson's disease focuses on medications that reduce excessive copper levels and prevent further accumulation, including:

• Copper Chelating Agents: Drugs like Penicillamine and Trientine bind to copper, promoting its elimination via urine. Penicillamine can lead to side effects like allergic reactions and potential kidney issues, while trientine is often better tolerated. Both drugs could initially exacerbate neurological symptoms, thus needing careful monitoring.

• Zinc Acetate: This medication inhibits copper absorption in the intestines and is commonly used as maintenance therapy post initial copper level reduction.

Lifelong adherence to medication is crucial for managing Wilson's disease effectively, avoiding severe complications. Regular medical follow-ups are necessary to monitor treatment success and manage any side effects.

Prevention

As a genetic disorder, Wilson's disease itself can't be prevented through lifestyle or environmental changes. Here's how one can mitigate risks:

• Genetic Counseling: Those with a family history should consider genetic counseling to evaluate the risk of transmitting the disease to offspring.

• Genetic Testing: This can help in early detection and intervention for family members, avoiding severe health complications.

• Management Post-Diagnosis: Once diagnosed, managing the condition involves monitoring copper levels through prescribed medication and dietary adjustments.
